Abstract

Has been fabricated and characterized an organic solar cell based onCopper phthalocyanine (CuPc) and 3, 4, 9, 10 perylenetetracarboxylic diimide(PTCDI). CuPc and PTCDI layer sandwiched between two different electrode ofITO and Ag by vacuum evaporation so solar cell structure isITO/CuPc/PTCDI/Ag. UV-Vis spectra of ITO/CuPc/PTCDI/Ag is 400 nm to 760nm which is superposition of CuPc layer and PTCDI layer. From characterizationof current density – voltage (J-V) show that current under illumination higher thandark current. The power conversion efficiency of 0.40 % under illumination 100mW/cm2 are obtained with fill factor 0.33.

Abstract

STUDY OF COMPOSITION AND HOMOGENITY OF Ni80Fe20 PERMALLOY IN THE FORM OF TARGET AND THIN FILM AS MATERIALS OF MAGNETIC SENSORS. Material fabrication of a ferromagnetic permalloy Ni80Fe20 has successfully been done. The sample was used as a target in magnetic thin film deposition by the sputtering method. The corresponding characterization including spectral analysis with XRF and XRD supports the prediction that the permalloy has been formed. The XRF analysis result shows that the ratio of the target has good agreement with the calculation. The thin film produced by sputtering gave the same characteristic as the target. From the XRD analysis it was shown that Ni80Fe20 permalloy was formed in the target and thin film, they were shown with the peak at the angle of 2θ= 44,4°, at a (111) plane orientation as the hkl plane from Ni80Fe20. There is another peak at the angle 2θ = 37° that was estimated to be ferrosic oxide Fe3O4. This magnetic oxide was formed when the target had been heated at the temperature 350°C-400°C in the free air.

Abstract

ANNEALING TEMPERATURES’ EFFECTS ON MICROSTRUCTURE AND OPTICAL PROPERTIES OF Ba0.95Sr0.05TiO3 FILMS. Ferroelectric materials, one of which is Barium Strontium Titanate (BST), can be applied for photovoltaic. Ferroelectric films function as the P-type semiconductor in the P-N junction. BST (Ba0.95Sr0.05TiO3) films have been deposited on Pt/Si (111) and quartz substrates via the CSD method prepared by spin coater. The films were annealed at various temperatures of 800 °C, 900 °C, and 1000 °C to observe the annealing temperatures' effects on the microstructure and optical properties of the BST films. From the XRD results, the intensity of diffraction peaks gets higher along with the higher annealing temperature. It thus causes the level of crystallization and the crystal size of the Ba0.95Sr0.05TiO3 films to increase. The morphology results reveal that the grains size of the Ba0.95Sr0.05TiO3 films is getting larger with the higher annealing temperature. The optical properties examined in the Ba0.95Sr0.05TiO3 films include absorbance and bandgap energy values. Values of bandgap energy show a decrease with increasing sintering temperature. The smallest bandgap energy of the Ba0.95Sr0.05TiO3 film is achieved at 1000 °C of 3.20 eV. BST films were annealed at temperature 1000 °C attained from this study can be considered as candidate for a photovoltaic ferroelectric material.

Abstract

DSSC was kind of solar cell based on dye as sensitizer or photon absorber. Scattering layer method used to optimize photon scattered process on working electrode. In this research, variation temperature annealing of scattering layer have done to find out the effect toward DSSC’s efficiency. TiO2 nanopowder and TiO2 transparent are used as semiconductor layer and scattering layer, respectively which deposited with spin coating method. Platinum was deposited on counter electrode with brush painting method. TiO2 nanopowder was annealed at 400oC, while scattering layer were annealed at variation temperature i.e. 400oC, 450oC, 500oC, and 550oC. Dye Ruthenium Complex N719 was used as sensitizer on DSSC’s structure. Result of XRD characterization on working electrode show that highest crystallite size is 18.92 nm with annealing process of scattering layer at 450oC and decreased when the temperature is over 400oC. Photovoltaic characterization used Keithley I-V meter. The annealing process of scattering layer at temperature 450oC has good photovoltaic parameter. This cell has short circuit current (Isc) is  A, open circuit voltage (Voc) is 0.39 V, and fill factor is 0.51. The value of Voc was influenced by the absorption of dye in TiO2 layer. Annealing scattering layer at 450oC produce crystallite structure with higher TiO2 surface area, it can optimize photon absorption of dye more than the annealing process over 450oC. Scattering layer which annealing at 450oC can increase efficiency of DSSC cells from  % to  %.
